Subject: Re: Best type of iron for a solenoid

Post:

Stephen and Tappers all,

I have found that the best core for a solenoid is to use copper coated
welding rod. The stuff I used came in 3/32 inch diameter and was 3 or 4
foot long. We just cut the stuff to length ( which turned out to be a job
because we had to cut each piece individually ) and then used as much as
we needed to get the diameter coil that we desired. In my case I ended up
with 4 ea. 1/5 inch cores that were 14 inches long which look as good
today as when they were made a decade ago.
When we tested the cores, we could find no detectable difference between
the uncoated iron cores we were replacing and the new copper coated
welding rod cores.

Later,
Dale
